Application filed Cetober 1917.

To all whom it may concern it known that I. HA4 one EDGAR You now, asubject of the King of Great Britain, residing in Glasgow, Scotland,have in o vented a certain new one useful ater- Cooled Valve for Closingthe Finnels oi Submarine Vessels, of which the following is aspecification.

The invention relates to means for closing the aperture a 'nnnel of asubmarine vessel to prevent access of water when the vessel issubmergec.

luscordingto the invention, the aperture is closed by a slide valve.which is water cooled both in the open and closed positions by thecirculation or" water, which enters the valve chest by one orifice andleaves bf." another.
